Homework Statement
:[/B] A uniform wire of linear mass density λ having three sides each of length 2a is kept on a smooth horizontal surface. An impulse J is applied at one end as shown in the figure. P is the midpoint of AB. Now answer the following questions.1) The angular velocity of system just after the impulse?
Sorry the image is poorly lit.
Homework Equations
: [/B]Conservation of angular momentum, Iω = JrWhere R is perpendicular distance of Point of application of J from hinge point.
The Attempt at a Solution
:[/B]I want to know which point should i consider hinge point. Is it the other end of the rod commected to B and⊥ AB?
